Victron SmartSolar MPPT 250/70-MC4

The Smartsolar MPPT 250/70-MC4 from Victron Energy (MPN SCC125070310) is part of the latest generation of smart solar controllers from the Dutch premium manufacturer. The controller processes a whopping 70A of solar power and can work flexibly with 12/24/36/48 V batteries, with a maximum PV input voltage of 250V DC. Ultra-fast power tracking and automatic power point detection in partial shade are just two of the many highlights of this new device class. In addition, this model can be operated in parallel with other controllers of the same type.

Compared to the Smartsolar 150/..... series, the 250/.... series can handle a maximum PV input voltage of 250V. This is also one of the reasons why the 250 solar controller family has been able to increase its efficiency by another 1 percent to a total of 99%, setting new standards in the industry. This is currently the best value among all solar charge controllers we know of. Compared to the BlueSolar family, the Bluetooth module is already integrated into the 250 SmartSolar series, making the Smart Dongle unnecessary for this device if you want to analyze and configure the controller via Bluetooth using a smartphone or tablet. Another new feature is the optional LCD display, which can be easily attached to the SmartSolar 250/70-MC4 as needed. The display then provides all important information about the controller. If required, the MPPT WireBox-MC4 from Victron Energy is the ideal addition to your SmartSolar charge controller. It securely covers the cable entries and connection terminals of the controller, protecting them from external influences and contact.

smart configuration and analysis via Victron Connect app

Modern Apple and Android smartphones, tablets, Macbooks, and other devices can be connected thanks to the built-in Bluetooth module and the free Victron Connect app. The app can then be used to configure many important functions of the SmartSolar controller. Of course, it also provides all important parameters such as the current solar yield in real time.

automatic detection of the maximum power point in case of partial shading

In the event of partial shading, there may be two or more maximum power points (MPP) on the current-voltage curve. Conventional MPPTs tend to adjust to a local MPP. However, this may not be the optimal MPP. The innovative algorithm of the SmartSolar controller will always maximize energy yield by adjusting to the optimal MPP.

Latest generation high-speed MPP tracker

Especially when the sky is overcast and the light intensity is constantly changing, an extremely fast MPPT controller improves energy yield by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers.

optional LCD display available for retrofitting

If you prefer to operate and configure the Smartsolar MPPT 250/70-MC4 directly, you can retrofit the Smartsolar Control SCC900600010 display. The display allows easy configuration of the controller via key input and also provides all important performance data at a glance.

comprehensive electronic protection

• Protection against reverse battery connection
• PV reverse current block
• Protection against device overheating
• Protection against short circuits
• Protection against reverse polarity PV connection

the VE.Direct data communication port

VE.Direct in text mode transmits all important parameters to other devices connected to the charge controller every second, thus enabling communication with additional devices such as the GX Color Control system panel. The VE.Direct connection is intended for products where full Canbus integration (VE-Direct) would be too costly. For more information about VE.Direct, please visit our Victron Energy brand shop.

optionally also available as a version with screw terminals

The 250/70-MC4 is also available as a version with 35mm screw terminals on the solar side of the charge controller instead of the MC4 connectors, which you can find here.
